Fiber optic variable attenuator using a thermal lens induced in a dichroic polarizer
TLDR
In this paper, a fiber optic variable attenuator using a dichroic polarizer sheet illuminated by a heating beam is described, which allows one to control the amount of light to be coupled into an optical fiber.Abstract:
A fiber optic variable attenuator using a dichroic polarizer sheet illuminated by a heating beam is described. The light absorbed by the polarizer induces a thermal lens, which allows one to control the amount of light to be coupled into an optical fiber. Some experiments demonstrating the thermal lens action are presented.read more
